I have also ordered another version. This one is advertised as a I2c bus but it isn't in the true sense of I2c.
It uses any 2 x IO pins with the library.
The library looks pretty simple and work well on the the Mega 2560. I Haven't quite got it working on a wemos yet.
Dear friends.
I tried using Wemos with the library posted above for TTP229 module but the Wemos exhibits : SoftWDT reset . Naturally the same result is obtained if I use inline C. Some library must be causing it. Gurus in forum please have a look!
